5.2.4 Notes on CAPWAP

This section lists some additional features of ZyXEL's implementation of the
CAPWAP protocol.
• When the AP controller uses its internal Remote Authentication Dial In User
Service (RADIUS) server, managed APs also use the AP controller's
authentication server to authenticate wireless clients.
• Only one AP controller can exist in any single broadcast domain.
• If a managed AP's link to the AP controller is broken, the managed AP continues
to use the wireless settings with which it was last provided.
